Basics of Ion Exchange FTLOScience

WebThe process of treating permanent hardness of water using synthetic resins is based on the exchange of cations (e.g., N a+,Ca2+,M g2+ etc) and anions (e.g., Cl−,SO2− 4,HCO− 3 etc) present in water by H+ and OH− ions respectively. Synthetic resins are of two types: 1) Cation exchange resins. 2) Anion exchange resins. WebOct 22, 2024 · The exchange occurs on a material known as the resin, which is saturated with a different ion than the one it is removing. Usually, sodium (Na +) or protons (H +) are the ions of choice in water treatment; the equation for exchange is: 2 R-Na + + Ca 2+ → R 2 -Ca 2+ + 2 Na + (where R denotes the resin material) snow predictions for georgia 2022
